The nation set to elect female prime minister in historic first
Over the last two decades, Japan has seen more than 10 leaders.
Actually, one expert likens taking up the country's highest office to taking a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? This is partly because of it being a "one-party democracy", explains Prof James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry originates inside the party, instead of from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all want their own faction to get the top job."
"So even though you might be chosen as prime minister, the moment you're in power, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- One-party dominance restricts outside challenges
- Internal factional rivalries fuel power struggles
- The prime minister's position is often described as a "cursed position"
- Political stability stays elusive despite economic strength
